A Pilot Randomized Controlled Trial of Augmented Reality Just-in-Time Guidance for the Performance of Rugged Field Procedures.

INTRODUCTION: Medical resuscitations in rugged prehospital settings require emergency personnel to perform high-risk procedures in low-resource conditions. Just-in-Time Guidance (JITG) utilizing augmented reality (AR) guidance may be a solution. There is little literature on the utility of AR-mediated JITG tools for facilitating the performance of emergent field care. STUDY OBJECTIVE: The objective of this study was to investigate the feasibility and efficacy of a novel AR-mediated JITG tool for emergency field procedures. METHODS: Emergency medical technician-basic (EMT-B) and paramedic cohorts were randomized to either video training (control) or JITG-AR guidance (intervention) groups for performing bag-valve-mask (BVM) ventilation, intraosseous (IO) line placement, and needle-decompression (Needle-d) in a medium-fidelity simulation environment. For the interventional condition, subjects used an AR technology platform to perform the tasks. The primary outcome was participant task performance; the secondary outcomes were participant-reported acceptability. Participant task score, task time, and acceptability ratings were reported descriptively and compared between the control and intervention groups using chi-square analysis for binary variables and unpaired t-testing for continuous variables. RESULTS: Sixty participants were enrolled (mean age 34.8 years; 72% male). In the EMT-B cohort, there was no difference in average task performance score between the control and JITG groups for the BVM and IO tasks; however, the control group had higher performance scores for the Needle-d task (mean score difference 22%; P = .01). In the paramedic cohort, there was no difference in performance scores between the control and JITG group for the BVM and Needle-d tasks, but the control group had higher task scores for the IO task (mean score difference 23%; P = .01). For all task and participant types, the control group performed tasks more quickly than in the JITG group. There was no difference in participant usability or usefulness ratings between the JITG or control conditions for any of the tasks, although paramedics reported they were less likely to use the JITG equipment again (mean difference 1.96 rating points; P = .02). CONCLUSIONS: This study demonstrated preliminary evidence that AR-mediated guidance for emergency medical procedures is feasible and acceptable. These observations, coupled with AR's promise for real-time interaction and on-going technological advancements, suggest the potential for this modality in training and practice that justifies future investigation.

A mobile integrated health program for the management of undifferentiated acute complaints in older adults is safe and feasible.

BACKGROUND: Poor care access and lack of proper triage of medical complaints leads to inappropriate use of acute care resources. Mobile integrated health (MIH) programs may offer a solution by providing adaptable on-demand care. There is little information describing programs that manage undifferentiated complaints in the community. The objective of this study was to assess the safety and feasibility of an MIH program that responds to the community to manage medical complaints in older adults. METHODS: This was a prospective observational study examining a pilot MIH program. Seven ambulatory clinics and their affiliated patients aged 65 and older were oriented to the program and invited to use its services. Visit and follow-up data for all patients who underwent an MIH visit were abstracted, along with 30-day follow-up information. All demographic data and outcomes were reported descriptively. RESULTS: In 21 months, 153 MIH visits were completed, involving 91 patients (mean age 81 years, 60.4% female). The most common chief complaints were generalized weakness (28.8%) and shortness of breath (18.9%). Electrocardiogram (57.5%) and point-of-care bloodwork (34.6%) were the most common diagnostic tests performed. Sixteen visits (10.4%) were followed by an emergency department (ED) visit within 72 h. In 11 encounters, the patient was referred to the ED; in five cases, the ED visit was unforeseen. Fifteen patients (9.8%) were admitted to the hospital after an MIH visit. There were two deaths within 30 days following an index visit. CONCLUSIONS: An MIH program designed to address the acute complaints of community-dwelling older adults was feasible and safe, with low rates of unforeseen emergency services utilizations. MIH programs have valuable diagnostic and therapeutic capabilities and may serve to help triage the acute medical needs of patients. Further study is required to validate the efficacy and cost-effectiveness of MIH programs.

A Citywide Approach to SARS-CoV2 Testing.

The COVID-19 pandemic caused more than 30 million infections in the United States between March 2020 and April 2021. In response to systemic disparities in SARS-CoV2 testing and COVID-19 infections, health systems, city leaders and community stakeholders in Worcester, Massachusetts created a citywide Equity Task Force with a specific goal of making low-barrier testing available to individuals throughout our community. Within months, the state of Massachusetts announced the Stop the Spread campaign, a state-funded testing venture. With this funding, and through our community-based approach, our team tested more than 48,363 individuals between August 3, 2020 and February 28, 2021. Through multiple PDSA (Plan-Do-Study-Act) cycles, we optimized our process to test close to 300 individuals per hour. Our positivity rate ranged from 1.5% with our initial testing events to a high of 13.4% on January 6, 2021. During the challenges of providing traditional inpatient and ambulatory care during the pandemic, our health system, city leadership, and community advocacy groups united to broaden the scope of care to include widespread, population-based SARS-CoV2 testing. We anticipate that the lessons learned in conducting this testing campaign can be applied to further surges of SARS-CoV2, international environments, and future respiratory disease pandemics.

Patient Outcomes Following Ketamine Administration for Acute Agitation with a Decreased Dosing Protocol in the Prehospital Setting.

BACKGROUND: Agitated behaviors are frequently encountered in the prehospital setting and require emergent treatment to prevent harm to patients and prehospital personnel. Chemical sedation with ketamine works faster than traditional pharmacologic agents, though it has a higher incidence of adverse events, including intubation. Outcomes following varying initial doses of prehospital intramuscular (IM) ketamine use have been incompletely described. OBJECTIVE: To determine whether using a lower dose IM ketamine protocol for agitation is associated with more favorable outcomes. METHODS: This study was a pre-/post-intervention retrospective chart review of prehospital care reports (PCRs). Adult patients who received chemical sedation in the form of IM ketamine for agitated behaviors were included. Patients were divided into two cohorts based on the standard IM ketamine dose of 4mg/kg and the lower IM dose of 3mg/kg with the option for an additional 1mg/kg if required. Primary outcomes included intubation and hospital admission. Secondary outcomes included emergency department (ED) length of stay, additional chemical or physical restraints, assaults on prehospital or ED employees, and documented adverse events. RESULTS: The standard dose cohort consisted of 211 patients. The lower dose cohort consisted of 81 patients, 17 of whom received supplemental ketamine administration. Demographics did not significantly differ between the cohorts (mean age 35.14 versus 35.65 years; P = .484; and 67.8% versus 65.4% male; P = .89). Lower dose subjects were administered a lower ketamine dose (mean 3.24mg/kg) compared to the standard dose cohort (mean 3.51mg/kg). There was no statistically significant difference between the cohorts in intubation rate (14.2% versus 18.5%; P = .455), ED length of stay (14.31 versus 14.88 hours; P = .118), need for additional restraint and sedation (P = .787), or admission rate (26.1% versus 25.9%; P = .677). In the lower dose cohort, 41.2% (7/17) of patients who received supplemental ketamine doses were intubated, a higher rate than the patients in this cohort who did not receive supplemental ketamine (8/64, 12.5%; P <.01). CONCLUSION: Access to effective, fast-acting chemical sedation is paramount for prehospital providers. No significant outcomes differences existed when a lower dose IM ketamine protocol was implemented for prehospital chemical sedation. Patients who received a second dose of ketamine had a significant increase in intubation rate. A lower dose protocol may be considered for an agitation protocol to limit the amount of medication administered to a population of high-risk patients.

Paramedic Pain Management Practice with Introduction of a Non-opiate Treatment Protocol.

INTRODUCTION: There is concern about the initiation of opiates in healthcare settings due to the risk of future misuse. Although opiate medications have historically been at the core of prehospital pain management, several states are introducing non-opiate alternatives to prehospital care. Prior studies suggest that non-opiate analgesics are non-inferior to opiates for many acute complaints, yet there is little literature describing practice patterns of pain management in prehospital care. Our goal was to describe the practice patterns and attitudes of paramedics toward pain management after the introduction of non-opiates to a statewide protocol. METHODS: This study was two-armed. The first arm employed a pre/post retrospective chart review model examining medication administrations reported to the Massachusetts Ambulance Trip Information System between January 1, 2017-December 31, 2018. We abstracted instances of opiate and non-opiate utilizations along with patients' clinical course. The second arm consisted of a survey administered to paramedics one year after implementation of non-opiates in the state protocol, which used binary questions and Likert scales to describe beliefs pertaining to prehospital analgesia. RESULTS: Pain medications were administered in 1.6% of emergency medical services incidents in 2017 and 1.7% of incidents in 2018. The rate of opiate analgesic use was reduced by 9.4% in 2018 compared to 2017 (90.6% vs 100.0%). The absolute reduction in opiate use in 2018 was 3.6%. Women were less likely (odds ratio [OR] = 0.78, 95% confidence interval [CI], 0.69-0.89) and trauma patients were more likely to receive opiates (OR = 2.36, CI, 1.96-2.84). Mean transport times were longer in opiate administration incidents (36.97 vs 29.35 minutes, t = 17.34, p<0.0001). We surveyed 100 paramedics (mean age 41.98, 84% male). Compositely, 85% of paramedics planned to use non-opiates and 35% reported having done so. Participants planning to use non-opiates were younger and less experienced. Participants indicated that concern about adverse effects, efficacy, and time to effect impacted their practice patterns. CONCLUSION: The introduction of non-opiate pain medication to state protocols led to reduced opiate administration. Men and trauma patients were more likely to receive opiates. Paramedics reported enthusiasm for non-opiate medications. Beliefs about non-opioid analgesics pertaining to adverse effects, onset time, and efficacy may influence their utilization.

How will disaster victims react to first responder commands-A survey of simulated disaster victims.

OBJECTIVE: To determine whether victim behavior and interaction with triage personnel would conform to expected actions as dictated by the Simple Triage and Rapid Treatment (START) triage methodology, which emphasizes that victims will accept their assigned -triage category. METHODS: In total, 105 volunteers were recruited to complete a 32-question survey after portraying victims in a triage-focused mass casualty incident (MCI) simulation. Questions included sociodemographic characteristics, willingness to follow commands of first responders, and willingness to help first responders. The authors examined whether the outcomes differed by demographics, healthcare experience, or disaster exposure of participants. RESULTS: The survey response rate was 90 percent (95/105). The mean age of participants was 31 years (58 percent women). Half of respondents indicated that they would ask responders to change their triage color if they disagreed with it and 75 percent would ask first responders to change their friend or family members' triage colors. Twenty-one percent of victims reported that they would alter their own triage tag to receive treatment faster and 38 percent would alter a friend or family member's triage color. The youngest (<20 years) and oldest (>40 years) respondents were most likely to act maladaptively. CONCLUSION: Triage algorithms rely upon -victims following the instructions of rescuers. This study suggests that maladaptive behavior by some victims should be anticipated.

Code Help: Can This Unique State Regulatory Intervention Improve Emergency Department Crowding?

INTRODUCTION: Emergency department (ED) crowding adversely affects multiple facets of high-quality care. The Commonwealth of Massachusetts mandates specific, hospital action plans to reduce ED boarding via a mechanism termed "Code Help." Because implementation appears inconsistent even when hospital conditions should have triggered its activation, we hypothesized that compliance with the Code Help policy would be associated with reduction in ED boarding time and total ED length of stay (LOS) for admitted patients, compared to patients seen when the Code Help policy was not followed. METHODS: This was a retrospective analysis of data collected from electronic, patient-care, timestamp events and from a prospective Code Help registry for consecutive adult patients admitted from the ED at a single academic center during a 15-month period. For each patient, we determined whether the concurrent hospital status complied with the Code Help policy or violated it at the time of admission decision. We then compared ED boarding time and overall ED LOS for patients cared for during periods of Code Help policy compliance and during periods of Code Help policy violation, both with reference to patients cared for during normal operations. RESULTS: Of 89,587 adult patients who presented to the ED during the study period, 24,017 (26.8%) were admitted to an acute care or critical care bed. Boarding time ranged from zero to 67 hours 30 minutes (median 4 hours 31 minutes). Total ED LOS for admitted patients ranged from 11 minutes to 85 hours 25 minutes (median nine hours). Patients admitted during periods of Code Help policy violation experienced significantly longer boarding times (median 20 minutes longer) and total ED LOS (median 46 minutes longer), compared to patients admitted under normal operations. However, patients admitted during Code Help policy compliance did not experience a significant increase in either metric, compared to normal operations. CONCLUSION: In this single-center experience, implementation of the Massachusetts Code Help regulation was associated with reduced ED boarding time and ED LOS when the policy was consistently followed, but there were adverse effects on both metrics during violations of the policy.

Ambulatory care by disaster responders in the tent camps of Port-au-Prince, Haiti, January 2010.

On January 12, 2010, a magnitude 7.0 earthquake occurred approximately 10 miles west of Port-au-Prince, Haiti, and created one of the worst humanitarian disasters in history. The purpose of this report is to describe the types of illness experienced by people living in tent camps around the city in the immediate aftermath of this event. The data were collected by a team of medical personnel working with an international nongovernmental organization and operating in the tent camps surrounding the city from day 15 to day 18 following the earthquake. In agreement with the existing literature describing patterns of illness in refugee and internally displaced populations, the authors note a preponderance of pediatric illness, with 53% of cases being patients younger than 20 years old and 25% younger than 5 years old. The most common complaints noted by category were respiratory (24.6%), gastrointestinal (16.9%), and genitourinary (10.9%). Another important feature of illness among this population was the observed high incidence of malnutrition among pediatric patients. This report should serve as a guide for future medical interventions in refugee and internally displaced people situations and reinforces the need for strong nutritional support programs in disaster relief operations of this kind.
